Abstract: 376,804. Electrically tripped switches; self-supporting resistances. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Chapman, C. H. ; 216, Glen Avenue, Scotia, New York, U.S.A.) March 16, 1931, No. 8035. Convention date, March 18, 1930. [Class 38 (v).] An electric heater 25 for bi-metallic thermal relays comprises a flat bar 26 having one or more heat-conducting tongues 27 extending from one or other of its longitudinal edges and looped round so as to form a sheath in which the bimetal strip 15 is located, the tongue 27 providing increased heat-storage capacity and preventing burn-out of the heater on overload. The tongues 27 may extend alternately from opposite edges of the bar 26. An electromagnetically operated switch 10 for heavy currents is mounted on a base 11 carrying terminal supports 12, 13 on which the bimetallic unit 15, 32 is carried. This unit is formed of an L-shaped channel member 14 flanged at 32 and secured to the support 12, and having an arm 16 pivoted at 17, controlled by a spring 18 and held against said spring by the free end 15<1> of the bi-metal strip 15 which is secured to the member 14. The heater 25 surrounds the strip 15 and is mounted on the supports 12, 13, the arm 16 being positioned under a trip bar 19 in the assembled position. When the strip 15 is flexed, due to excessive current, the arm 16 is released and trips the bar 19, which is pivoted at 20, to open the contacts 21, 22 and de-energize the holding magnet of the switch.

Patent GB-404497-A (GB)
Title: Improvements in and relating to electric switches operated by gas under pressure
IPC: H01H3/52
Filed: 1933-03-16
Abstract: 404,497. Arc-rupturing in switches. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. March 16, 1933, No. 8053. Convention date, March 16, 1932. [Class 38 (v).] Pneumatic-actuation ; retarding devices.-In pressure-gas operated switches, in which, in opening, the distance between the contacts is rapidly increased until that required for extinguishing the arc is reached, and, after the extinction is completed, the distance is again increased to that requisite for permanently insulating the voltage, the movable contact has an oscillating motion imparted to it such that it reverses its direction of motion at least once within the extinguishing zone. Thus, pressure-gas is applied to the upper face of piston 6 carrying the movable contact, so that, the valve 8 being opened just previously, the piston moves rapidly down in the cylinder 7 and strikes a disc 11 urged upwards by a spring 12. The gas beneath the disc 11 is unable to escape through the space 10 to a sufficient extent, so it becomes compressed and finally reverses the motion of the piston. During the slow final opening stage, the gas leaks through the clearance 10, or a valve may be provided to let it out. In another form, Fig. 3 (not shown), a heavy mass is supported on a gas cushion and /or spring, with a buffer to bring the mass to rest at the end of its down stroke. The Specification also refers to the dimensioning of the outlet 8 and inlet 13 whereby the existing cylinder can be utilized for providing a gas cushion to effect the recoil.

Title: Improvements in or relating to serial number printing apparatus
Inventor: TURNER FREDERICK JAMES LESLIE
IPC: H04L12/08
Filed: 1962-03-02
Abstract: 927,983. Number-printing apparatus. CREED & CO. Ltd. March 2, 1962, No. 8161/62. Class100 (2). Apparatus for printing numbers on data bearing media such as perforated tapes used in data processing systems and teleprinters comprises a plurality of type wheels 1 arranged in a row, means for setting one or more of the wheels to positions indicative of a number to be printed, a hammer 22 for striking a tape T in such a manner as to move it towards the wheels 1, an inking tape or ribbon 21 disposed between the tape T and the wheels 1, a solenoid 31 for operating the type-wheel setting means and said hammer, and a latch 13 for retaining the hammer in an inoperative position until the type-wheels have been set. On energization of the solenoid 31a plunger 30 and a link 18 are drawn downwardly and an operating arm 9 is caused to pivot in an anticlockwise direction about spindle 7 against a spring 19, the hammer 22 mounted in a spring blade 10 being held stationary by the latch 13 which engages the end of the hammer stock 8. The movement of the arm 9 causes an increase in the tension in a spring 12 and causes an operating bar 6 to pivot a pawl-arm 5 in a clockwise direction about the axis 3 of the wheels 1 so as to effect movement of the respective type wheel through one digit position. Each wheel 1 is associated with a ratchet-wheel 4 having a co-operating pawl 17 mounted on a pawl arm 5. Further movement of the arm 9 causes a pin 15 mounted thereon to engage the latch 13 which is thereby disengaged from the hammer stock which pivots about axis 7 under the action of the spring 12 until an adjustable screw 11 engages the arm 9. The inertia of the head 22 causes it to strike the tape T which is forced down against the ribbon 21 and the wheels 1 to effect printing.

Patent GB-775818-A (GB)
Title: A process for removing dust from gases
IPC: C21B3/06
Filed: 1955-03-23
Abstract: Dust, particularly iron oxide dust, is removed from hot gases by contacting the dust-laden gases with hot slags or slag-forming materials which are capable of chemically incorporating the dust material to form relatively low-melting slags.  Suitable slag-forming materials which may be used are silica, silicates, calcium oxide, alumina or aluminium compounds, calcium fluoride, phosphorous compounds, e.g. P2O5, boric acid and its compounds, and alkali compounds, e.g. sodium silicate or sodium carbonate, either alone or in the form of a combination of two or more components giving highly fluid slags.  The fluidity of the slag may be increased or the melting temperature may be lowered by adding materials such as fluorspar, bauxite, low-fusing clays, fireclay, sodium carbonate, boric acid, or potassium or sodium glasses, alone or in a mixture containing several components. Slag-forming substances and/or fluxes may be periodically or continuously fed to the melt.  If heat is required, other than that provided by the sensible heat of the hot gases, it may be provided by burning part or all of the CO contained in the gases. A suitable slag formed from quartz sand and lime with an addition of iron oxide contained e.g. 31 per cent SiO2, 49 per cent FeO and 20 per cent CaO and had a melting temperature of 1205 DEG C.

Abstract: 738,198. Raising derrick masts. MOORE CORPORATION, L. C. March 30, 1953 [Sept. 5, 1952], No. 8693/53. Class 78 (4). A gin pole 16, Fig. 1, and welldrilling mast 10, 11, raised in succession by traction on a cable system joining them, carry co-operating rollers 30 and guides 31 (see also Fig. 4) so arranged that, during erection, the mast swings past its upright position to which it then returns under the action of gravity; the free return moment renders less critical the moment at which the traction must be removed. In the construction 'illustrated the mast .and gin pole are mounted on a base 1 in the manner described in Specification No. 738,195, to which the Specification refers, but the sling 21 for raising them passes directly from the travelling block 17 over pulleys 22 at the top of the gin pole to anchorages on brackets 24 carried by the mast. Operation of the draw works 3 first raises the gin pole to the position shown in broken lines in Fig. 1 in which guys 26 are taut, and then raises the mast until guides 31, Fig. 4, on the insides of the legs of the mast engage rollers 30 at the top of the gin pole. Continued tension on the sling 21 raises the mast to a position beyond its upright position so that the rollers 30 are at the lowest points of the guides 31. The mast then falls back to its upright position while the rollers 30 move up the portion of the guides 31 at the left in Fig. 4 during which motion the sling 21 is slackened so indicating to the draw works operator that the winding drum should be declutched. The mast and gin pole are secured together when erected by hinged bolts 33 carried on the mast and engaging slotted brackets 35 on the gin pole. When the mast is to be lowered a line is first attached to it so that it may be drawn beyond its upright position until the rollers 30 are in engagement with the longer portion of the guides 31 and the mast and pole are then lowered under the control of the draw works.
